Seismology is the scientific study of earthquakes and the spread of elastic waves through the Earth or through other planet-like bodies. The field includes studies of earthquake effects, such as tsunamis in addition to diverse seismic sources such as tectonic, volcanic, oceanic, atmospheric, and artificial processes. A related field that utilizes geology to infer information regarding past earthquakes is paleoseismology. A recording of earth motion as a function of time is a seismogram. A...

Physics is a natural science involving the study of matter and its motion through space-time, along with related concepts such as energy and force. On a broader scale, it also involves the general analysis of nature, conducted in order to understand how the universe behaves.
Physics is one of the oldest academic disciplines, perhaps the oldest through its inclusion of astronomy. Physics was part of natural philosophy until the Scientific Revolution in the 16th century, when the natural...

Computational Mechanics is a scientific journal founded in 1986 and published monthly by Springer. The journal covers all aspects of computational mechanics and reports original research in the field. It focuses on areas that involve the rational application of mechanics, mathematics, and numerical methods in the practice of modern engineering.
Areas covered include solid and structural mechanics, multi-body system dynamics, constitutive modeling, inelastic and finite deformation response,...

Archives of Computational Methods in Engineering (ACME) is a scholarly journal that publishes reviews presenting developments in computational engineering. It also provides a forum for spreading results of research and advanced industrial practice in computational engineering with particular emphasis on mechanics and related fields. The editor-in-chief is Michael Kleiber, Institute of Fundamental Technological Research, Polish Academy of Sciences, Warsaw.
Areas of publication in the...

The Seismometer is an instrument designed to measure the motions of the ground. This includes seismic waves generated by earthquakes, nuclear explosions, and other seismic sources. Records of these activities allow seismologists to map the interior of the Earth, and locate and measure the size of the different sources.
There are also seismographs, which is sometimes used in place of the word seismometer. However, a seismograph is the older instrument in which the measuring and recording...

A pivoted catch designed to fall into a notch on a ratchet wheel so as to allow movement in only one direction (e.g. on a windlass or in a clock mechanism), or alternatively to move the wheel in one direction.
